3. Main topics to be worked on in future
Requirements for CIL for retroreflective devices – classes
Requirements for R´ (RA) for retroreflective devices/markings – classes
Colorimetric requirements – daytime and nighttime visibility enhanced visibility
Photometric measurement conditions – to define independent from device
Water-penetration test and corrosion test independend from the device
Weathering test (colour fasness) to adapt to state of the art testing
Mechanical requirements to define testing independend from device
Chemical and environmental requirements - testing independend from device
Specific requirements and testing, which is depending from the device
